0–100, higher is better. How it is calculated

CNL Invest operates the website Zadosti.cz, a Czech Republic-based platform offering a smart application designed to simplify the process of obtaining confirmations about the existence of engineering networks for construction projects. The company targets builders, IT infrastructure managers, and state employees, providing services that reduce administrative burdens and minimize risks related to errors and delays. The business is positioned as a niche service provider within the real estate and construction sector, founded in 2018, with a small company size and a focused market presence. Technically, the website is built on WordPress using the Elementor page builder, hosted on Azure DNS infrastructure. It employs modern web technologies including Google Tag Manager and Google Analytics for tracking and performance monitoring. The site demonstrates good SEO practices, mobile optimization, and basic accessibility features, delivering a moderate performance experience. From a security perspective, the site uses HTTPS with a good SSL configuration and includes a cookie consent mechanism compliant with GDPR. However, explicit security headers such as Content-Security-Policy and X-Frame-Options are not evident, and there is no visible security or incident response policy. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the website presents a professional and trustworthy digital presence with strong privacy compliance and a clear business focus. Strategic improvements in security headers and incident response documentation would enhance its security posture and trustworthiness.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

9 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

CNL Invest's business model revolves around providing a SaaS platform that streamlines the administrative process for construction-related network confirmations and IT infrastructure documentation. The company leverages partnerships, notably with zadosti.cz, to deliver its services. Its competitive advantage lies in simplifying complex bureaucratic procedures for builders and IT managers in the Czech Republic. The target customer segments include individual builders, IT infrastructure owners, and government employees. The company shows growth potential through digital transformation in the construction sector and maintains a focused partnership ecosystem. The website content and structured data reflect a clear and consistent brand message aligned with its market niche.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and GDPR-compliant cookie consent mechanisms in place. The absence of explicit security headers such as CSP, X-Frame-Options, and X-Content-Type-Options represents an area for improvement. No incident response or security policy pages were found, indicating a potential compliance gap. The use of third-party scripts like Google Tag Manager and analytics requires ongoing monitoring to mitigate risks. No vulnerabilities or sensitive data exposures were detected in the analyzed content. Overall, the security posture is adequate for the business scale but would benefit from enhanced security controls and documented incident response readiness.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Develop and publish explicit security and incident response policies to improve transparency and compliance.
  3. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are in use.
  4. Enhance website accessibility features to meet higher compliance standards and improve user experience.
  5. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.

Technical notes

Notes

The website is built on a modern WordPress CMS platform with Elementor as the page builder, hosted on Azure DNS infrastructure. It uses Google Tag Manager and Google Analytics for tracking and performance monitoring. The site has good SEO optimization with proper meta tags, Open Graph, and JSON-LD structured data. Performance is moderate with image optimization via ShortPixel. Mobile optimization is good, but accessibility features are basic. No broken elements or errors were detected in the HTML content. The technical stack is appropriate for the business size and market, with opportunities to improve security headers and accessibility compliance.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
